BACKGROUND Diarrhea is a common clinical manifestation of human immunodeficiency virus (HIV) infection. The important protozoan pathogens causing diarrhea include cryptosporidium, microsporidium, Isospora belli and cyclospora besides giardia lamblia and entamoeba histolytica. OBJECTIVE The objective of the present study was to determine the incidence of cyclospora (a coccidian protozoan) infection in HIV infected patients. METHODS Faecal smears were stained by modified acid fast staining method to demonstrate oocysts of cyclospora. RESULTS Out of 334 faecal specimens which were studied, cyclospora were identified in 22 cases (6.6 percent); and in 50 percent of the patients, there was a mixed infection with another protozoan parasite namely cryptosporidium. CONCLUSIONS Identification of this parasite is important because cyclosporiasis can be treated with trimethoprim-sulfamethoxazole. Outbreaks of cyclospora infection have been linked to waterborne transmission. Though adequately chlorinated water is free of coliforms, it can still contain cyclospora.

UI MeSH Term Description Entries
D007194 India A country in southern Asia, bordering the Arabian Sea and the Bay of Bengal, between Burma and Pakistan. The capitol is New Delhi. Republic of India
D003967 Diarrhea An increased liquidity or decreased consistency of FECES, such as running stool. Fecal consistency is related to the ratio of water-holding capacity of insoluble solids to total water, rather than the amount of water present. Diarrhea is not hyperdefecation or increased fecal weight. Diarrheas
